what I did to speed up development was, instead of building the source everytime (1.5 hrs in my pc), I'll just make another boot.img with my compiled kernel. boot.img contains the boot header, kernel image, ramdisk, and other stuff. To make the new boot.img, issue the "mkbootimg --cmdline 'no_console_suspend=1 console=null' --kernel <zImage> --ramdisk <ramdisk.img in the out/target/product/dream_open> - o boot.img" command. mkbootimg is located in out/host/linux-x86/bin. To flash boot.img to phone, "fastboot flash boot.img. Or you can overwrite the old boot.img with your new image so you can flash everything with "fastboot -w flashall".
Hope this can help.
